Abstract (en)

[origin: WO0032435A1] A cruise control system (1) for a vehicle (2), coupled to an engine management system (3) of the vehicle (2) is operable to alter the speed of the vehicle dependant upon input from the cruise control system (1). The cruise control system comprises: means (6, 8) for generating a measure V of the vehicle speed; means (3, 13) by which a driver of the vehicle (2) may set a desired cruise control speed; a cruise control digital display (16) for displaying to the driver a display equivalent v'c of the desired cruise control speed that is rounded according to a speed increment value I; a speedometer display (11) for displaying to the driver a display equivalent v's of the measure V of the vehicle speed; the display equivalent v' of a speed including a speed offset value O summed with the measure V of the vehicle speed. The cruise control system (1) adjusts if necessary the desired cruise control speed to an adjusted cruise control speed va in order to reduce any discrepancy in the display equivalent speeds v'c and v's, the adjusted cruise control speed va being calculated according to the following algorithm: a) the offset O is added to the measure V of the vehicle speed, and this total is divided by the speed increment value I to express the measure of the vehicle speed as a multiple of the speed increment value; b) said multiple is rounded according to speed increment value I to give a rounded multiple; and c) said rounded multiple is multiplied by the speed increment value I and the speed offset value O is substracted.
